Wheat-free 2007


Long ago, most of us made the change of reducing saturated fat in our diet. Few people now rely on butter (despite the idiotic butter vs. margarine controversy), full-fat dairy products, fried foods, and greasy meats. That's a healthy change, since saturated fat has conclusively been tied to various cancers, high blood pressure, rise in LDL, and is calorie-dense.

But if there were just one change you were to make beyond a reduction in saturated fat, a change that would translate into dramatic health benefits, it would be a drastic reduction, even elimination, of wheat products.

People do indeed eat enormous quantities of wheat flour-containing products. U.S. per capita consumption of wheat flour was 110 pounds in the early 1970s, and rose to 141 pounds in 1991. It's even higher now. 20% or more of most people's caloric intake every day is provided by wheat flour products.

Wheat containing foods are tasty and convenient. Witness the popularity of bagel shops, the goodie counter at Starbuck's, the proliferation of crackers, breads, and breakfast cereals at the grocery store. Patients are horrified when I suggest that they find a substitute for the sandwiches they eat every day. Even Mom said they were okay!

You're unlikely to hear much about this from the popular press. The wheat industry is enormous and exerts extraordinary clout, just like the drug industry. Texas alone farms 6 million acres of wheat, yielding over $2 billion for the state's economy. The "wheat chain" is complex and far-reaching: growers, processors, food manufacturers, the transportation industry, retailers, chemical producers, and on and on. Wheat futures are traded on the Chicago Board of Trade. Wheat is a major export industry for the U.S.

Of course, these are not evil people, intent on corrupting your health. In fact, most of them are probably working under the perception that they are raising a healthy product. The point is that the notion that wheat is healthy is deeply entrenched in the minds and economy of the U.S. Don't expect to hear unbiased commentary on the health effects of wheat products from most media sources.

What can you expect if you sharply reduce or eliminate wheat? The majority of people:

--Feel like a cloud has been lifted from their thinking.
--Don't experience the afternoon blah or tired feeling after lunch.
--Lose weight, sometimes substantial quantities.
--Raise HDL.
--Reduce small LDL.
--Reduce triglycerides, particularly if they start >100 mg/dl.
--Reduce blood sugar.

The reduction in small LDL can be especially impressive.

For most people, reducing or eliminating wheat is a sacrifice, a major change in food choices and even a loss of convenience. But the health benefits for most people can be dramatic.

Is vitamin D a "vitamin"?

Vitamins are crucial participants in the body's reactions and are obtainable from food. Vitamin C, for example, comes from citrus fruits and vegetables. Vitamin K comes from green vegetables. The B vitamins are found in meats, soy, dairy products, and grains. Vitamin A comes from carrots, squash, and other orange and green colored vegetables.

How about vitamin D? What foods contain vitamin D? The list includes:


Food International Units(IU) vitamin D per serving

Cod liver oil, 1 Tablespoon 1,360
Salmon, cooked, 3½ ounces 360
Mackerel, cooked, 3½ ounces 345
Tuna fish, canned in oil, 3 ounces 200
Sardines, canned in oil, drained, 1¾ ounces 250

Milk, nonfat, reduced fat, and whole, vitamin D fortified, 1 cup 98
Margarine, fortified, 1 Tablespoon 60
Pudding, prepared from mix and made with vitamin D fortified milk, ½ cup 50
Cheese, Swiss, 1 ounce 12

Ready-to-eat cereals fortified with 10% of the DV for vitamin D, ¾ cup to 1 cup servings (servings vary according to the brand) 40

Egg, 1 whole (vitamin D is found in egg yolk) 20
Liver, beef, cooked, 3½ ounces 15

(Modified from the Office of Dietary Supplements, National Institutes of Health)


You'll note that the only naturally-occurring food sources of vitamin D are the modest quantities in fish, egg yolks, and liver. All the other vitamin D-containing foods like cereal, milk, and other dairy products have vitamin D only because humans add it.

It takes me (personally) 6000 units of vitamin D per day to bring my blood level to an acceptable 50 ng/ml. To obtain this from eating salmon, I would have to eat 58 ounces, or 3 1/2 pounds of salmon--every day. Or, I could eat 30 cans of tuna fish.

If I didn't want to eat loads of fish every day, I could drink 60 glasses of milk every day. After I recovered from the diarrhea, my vitamin D might be adequate, provided the milk indeed contained the amount stated on the label (which it often does not when scrutinized by the USDA).

If vitamin D is a vitamin, how are humans supposed to get sufficient quantities? I don't know anybody who can eat 3 1/2 lbs of salmon per day, nor drink 60 glasses of milk per day. But aren't vitamins supposed to come from food?




The problem is that vitamin D is not really a vitamin, it's a hormone. If your thyroid hormone level was low, you'd gain 20, 30, or more pounds in weight, your blood pressure would skyrocket, you'd lose your hair, become constipated, develop blood clots, be terribly fatigued. In other words, you'd suffer profound changes. Likewise, if thyroid hormone levels are corrected by giving you thyroid hormone, you'd experience profound correction of these phenomena.

That's what I'm seeing with vitamin D: restoration of this hormone to normal blood levels (25-OH-vitamin D3 50 ng/ml) yields profound changes in the body.

If there's one thing that I've come across lately that packs extraordinary potential to help us in reducing heart scan scores, it's the vitamin--sorry, the hormone--cholecalciferol, or D3.

Heart scan curiosities 3


Note the shape of the chest in this 64-year old man. The front of his chest (upper portion of scan) is concave. In other words, if you were looking at this man (shirtless, of course) face to face, his chest would bow inward, rather than the usual outward configuration. The official name for this is "pectus excavatum".





Compare this to the normal chest in the second image, in which the chest is convex. Face to face, the chest would bow slightly outward.















What does it matter? The pectus excavatum in and of itself has no importance, just a curiousity. (I personally find this surprising, given the fact that the heart actually appears squashed by the sternum, or chest wall.) However, it is commonly associated with a "floppy" mitral valve (also called mitral valve prolapse), a common congenital disorder of the mitral valve often accompanied by a slender build, loose joints, and even a nervous disposition. Occasionally, in its more severe forms, the aorta is also enlarged. (This man's aorta is not enlarged.)

So, while we can't actually visualize the mitral valve by a CT heart scan, we can surmise that he likely has a floppy mitral valve, is slender, is probably a nervous sort, and has long limbs with loose joints. He probably required braces as a child, since many people have a phenemenon of "crowded teeth". The roof of his mouth, or hard palate, probably unusually high up in the mouth. He probably has a "weak chin", meaning a less prominent protuberance of his chin. His fingers and toes are likely unusually long and slender.

It could mean that some attention and exploration of how floppy his mitral valve might be could be useful, e.g., an ultrasound or echocardiogram. He might even require oral antibiotics at the time of any oral or some gastrointestinal procedures, since floppy valve are more susceptible to blood infections when potentially "dirty" orifices are instrumented.

All that from a heart scan!

Gratitude

The holidays and the end of the year may be a good time to reflect on how grateful we should be for having the freedom to discuss the ideas we share on this Blog, the Track Your Plaque website, online and offline.

Although I rant and rave against the status quo in heart disease, the shameful profiteering of my colleagues and hospitals, the cut-throat marketing practices of drug and device manufacturers, I am truly grateful that, in the U.S., I have the extraordinary freedom to say these things. You have the freedom to agree or disagree and none of us pays a price for truth.

I've been reflecting myself a great deal on this idea of happiness and gratitude being a critical component of coronary plaque regression and dropping your heart scan score. (See The Heart Scan Blog from earlier this week.) The more I think about this, the more I think that it is indeed true: Harboring anger and resentment, regrets, irritability, all those petty emotions that most of us know are not good for us, erode our chances for success in dropping your heart scan score.

We could rationalize it this way: Anger and other negative emotions are adrenaline-driven states, also characterized by activation of the "sympathetic" nervous system. (Despite its name, the sympathetic system is not sympathetic, as in compassionate; its the "fight-or-flight" activator that accelerates heart rate and blood pressure.)

Happiness, contentment, and gratitude are "parasympathetic" states characterized by slower heart rates, deeper respiration, greater variation in beat-to-beat heart rates (a powerful predictor for health and the basis for the HeartMath program of Lew Childre), lower blood pressure, and even a subtle change in brain waves. In other words, happiness is not just a mental and emotional state, it is a constellation of physical phenomena.

Even though I pick on Dr. Dean Ornish for his stubborn adherence to the outdated low-fat mantra, I do agree with him on the value of happiness. His book, Love and Survival, articulates this concept. Ornish has even said on several occasions that it wasn't the diet that was most important but the connection and warmth that was created by the comraderie created by participation in the Ornish Program group sessions.

I am personally grateful that the concepts I promote are gaining a following and that I can say so without fear of prosecution. I am grateful that Track Your Plaque followers are not just sharing our concepts, but obtaining genuine and powerful health advice that will help keep them home and healthy, away from hospitals, procedures, and the dangers of heart disease.

I hope you share in my gratitude and are thankful for all the truly wonderful things that surround us. I wish you all a wonderful holiday and long, healthy life filled with gratitude.

A Track Your Plaque failure

We recently had a man suffer a heart attack after beginning the program. Let me tell you the details.

Jerry's heart scan score 781, age 53. Multiple lipoprotein abnormalities: HDL 32 mg/dl, triglycerides 279 mg/dl, nearly all of his LDL was in small particles with an "effective" LDL (LDL particle number), and very high IDL. So Jerry added fish oil 6000 mg per day, niacin, and vitamin D to the statin drug prescribed by his primary physician. Jerry added oat bran, ground flaxseed, and tried to eat fish at least once per week.

However, Jerry continued to smoke. He'd smoked for 40 years (!), up to 2 packs per day, and just reasoned that it was too late to quit. He also continued to indulge in the packaged, processed foods that were part of his convenience story business.

Jerry's stress test was normal--no chest pain, normal EKG, normal images of blood flow, though he was somewhat breathless, likely from his lung disease from smoking.

Two months into his program, he abruptly experienced severe crushing pain in his chest. Because he was traveling, he ended up in a small local hospital. A failed angioplasty led to urgent coronary bypass surgery.

Jerry's alive. Now he's a non-smoker. He's got the pursed lips and peculiar breathing pattern that smokers get, but he's breathing.

Lesson: In the face of the most powerful program for heart disease known, it can still be overpowered by Twinkies, Hoho's, pretzels, chips--and cigarettes.

The new year is approaching. Be grateful for another year of healthy life and commit to a new year of even greater health. If you're a smoker, there's no choice: you've got to quit.

Are you more like a dog or a rabbit?

Dr. William Roberts, editor of the American Journal of Cardiology and cardiovascular pathologist, is a perennial source of clever ideas on heart disease.
In a recent editorial, Dr. Roberts comments:








"Because humans get atherosclerosis, and atherosclerosis is a disease only of herbivorers, humans also must be herbivores. Most humans, of course, eat flesh, but that act does not make us carnivores. Carnivores and herbivores have different characteristics. (1) The teeth of carnivores are sharp; those of herbivores, flat (humans have some sharp teeth but most are flat for grinding the fruits, vegetables, and grains we are built to eat). (2) The intestinal tract of carnivores is short (about 3 times body length); that of herbivores, long (about 12 times body length). (Since I am 6 feet tall my intestinal tract should be about 60 feet long. As a consequence, if I eat bovine muscle [steak], it could take 5 days to course through those 20 yards.) (3) Body cooling for carnivores is done by panting because they have no ability to seat; although herbivores also can pant, they cool their bodies mainly by sweating. (4) Drinking fluids is by lapping them for the carnivore; it is by sipping them for the herbivore. (5) Vitamin C is made by the carnivore's own body; herbivores obtain their ascorbic acid only from their diet. Thus, although most human beings think we are carnivores or at least conduct their lives as if we were, basically humans are herbivores. If we could decrease our flesh intake to as few as 5 to 7 meals a week our health would improve substantially."



You can always count on Dr. Bill Roberts to come up with some clever observations.

I think he's right. Some of the most unhealthy people I've known have been serious meat eaters. Most of the vegetarians have been among the healthiest. (I say most because if a vegetarian still indulges in plenty of junk foods like chips, crackers, breakfast cereals, breads, etc., then they can be every bit as unhealthy as a meat eater.)

Should you become a vegetarian to gain control over coronary plaque and other aspects of health? I don't believe you have to. However, modern livestock raising practices have substantially modified the composition of meats. A steak in 2006, for instance, is not the same thing as a steak in 1896. The saturated and monounsaturated fat content are different, the pattern of fat "marbling" is different, the lean protein content is different. Meat is less healthy today than 100 years ago.

Take a lesson from Dr. Roberts' tongue-in-cheek but nonetheless provocative thoughts. Pardon me while I chew on some carrots.

Are happy people more likely to reduce heart scan scores?

I was talking to Darryl, a patient today: 71 years old with a heart scan score of 378, as well as an enlarged aorta (4.5 cm).

We had identified numerous lipoprotein abnormalities 12 months ago and advised him on a program for correction. His patterns included small LDL, high triglycerides, sky-high IDL (VERY important when you have an enlarged aorta), and lipoprotein(a). Blood pressure was also high, another crucial fact to correct when the aorta is enlarged.

Anyway, Darryl corrected lipoproteins to perfection: basic lipids were substantially better than 60-60-60; lipoprotein(a) was reduced well into the desirable range; IDL was eliminated; blood pressure was 108/64. Repeat heart scan score: 354.

There's nothing spectacular about Darryl's story, except that, despite these issues, Darryl was a happy man. He smiled throughout our conversation. He has told me on several occasions how grateful he is for the life he has.

Darryl is not wealthy. He retired around 4 years ago and fills his day with helping his wife, walking outdoors, helping out at his church, and contributing to the care of his grandchildren. Through all this Darryl is incurably, unfailingly, and irrepressibly happy.

It made me think back through all the other people who've also had great succes in their Track Your Plaque program. It struck me that, for the most part, they too were a happy bunch: generally optimistic, happy, not overly stressed nor prone to extremely stressful responses to stressful situations. All seem to also be grateful for the good in their lives, though most had no more money than the average person and had their share of difficulties in life. In fact, I can only recall one person who reversed coronary plaque who was an angry, pessimistic personality. Just one.

Could it be that happy, optimistic people are more likely to reverse coronary plaque? It would, after all, be consistent with all the other observations that type A personalities have more heart attack, etc.

Anyway, this is just an informal observation but one that seems very consistent. Track your plaque--and be happy!

Don't overdo the vitamin D

As time passes and I advise more and more people to supplement vitamin D, I gain increasing respect for this powerful "vitamin". I am convinced that vitamin D replacement is the reason for a recent surge in our success rates in dropping CT heart scan scores. I believe it is also explains the larger drops we've been witnessing lately--20-30%.

But vitamin D can be overdone, too. Too much of a good thing . . .

Despite being labeled a "vitamin", cholecalciferol is actually a hormone. Vitamins are obtained from food and you can thereby develop deficiencies because of poor intake. Deficiency of vitamin C, for instance, arises from a lack of vegetables and fruits.

Vitamin D, on the other hand, is nearly absent from food. The only naturally-occuring source is oily fish like salmon and sardines. Milk usually has a little (100 units per 8 oz) because milk producers have been required by law to put it there to reduce the incidence of childhood rickets.

A woman came to me with a heart scan score of nearly 3800, the highest score I've every seen in a woman. (Record for a male >8,000!) She was taking vitamin D by prescription from her family doctor but at a dose of 150,000 units per week, or approximately 21,000 units per day. This had gone on for about 3-4 years. This may explain her excessive coronary calcium score. Interestingly, she had virtually no lipoprotein abnormalities identified, which by itself is curious, since most people have some degree of abnormality like small LDL. Obviously, I asked her to stop the vitamin D.

Should you be afraid of vitamin D? Of course not. If your neighbor is an alcoholic and has advanced cirrhosis, does that mean you shouldn't have a glass or two of Merlot for health and enjoyment? It's a matter of quantity. Too little vitamin D and you encourage coronary plaque growth. Too much vitamin D and you trigger "pathologic calcification", or the deposition of calcium in inappropriate places and sometimes to extreme degrees, as in this unfortunate woman.

Ideally, you should have your doctor check your 25-OH-vitamin D3 blood levels twice a year in summar and in winter. We aim for a level of 50 ng/ml, the level at which the phenemena of deficiency dissipate.

"It must have been the statin"

After four years of trying, Randy finally reduced her heart scan score. It not only dropped, it plummeted. After four previous scans that showed 25% or more increases, she'd finally dropped her score 23%. (I Blogged about Randy's case a few weeks ago.)

Randy also works for a cardiologist. When she told him that she had reversed her coronary plaque and reduced her heart scan score by 23%, he said, "It must have been the statin agent."

Randy was indeed on a statin drug at a low dose. But she also had taken great efforts in exercise, food choices, fish oil, and vitamin D. In fact, her score had progressed dramatically while she was taking the drug. Put simply, it was not the statin.

But that is the mindset of the conventionally thinking cardiologist. Stent, bypass, or statin drug--what else is there? Even with crystal clear evidence for coronary plaque regression, they refuse to acknowledge that tools that are not in their everyday consciousness could have achieved so spectacular a result.

Given a choice, 9 out of 10 cardiologists would rather put a stent in and walk away $2000 richer for an hour of work. Don't allow them to have this choice. Take control now.

Statin Drugs May Help the Healthy:
Cholesterol-Lowering Statin Drugs May Benefit People Without Heart Disease


That's the headline on WebMD, reporting the findings of a recent study published in the Archives of Internal Medicine. In reality, it wasn't really a study at all, but a re-analysis of previously published data, a so-called meta-analysis.

Nonetheless, the University of Toronto group re-analyzed the results of several studies, pooling data on 28,000 people, none of whom had known coronary disease. The results were similar to the results of the studies that were reported individually: a 29% reduction in heart attack and other "events" in people taking statin drugs.

What's surprising to me is this notion that statins, or any other treatment for that matter, prevent heart attack in people without heart disease. This is idiotic. Of course they had coronary heart disease. You can't have a heart attack in the absence of coronary disease. (There are very rare exceptions, like cocaine users, who experience coronary spasm from the drug).

What the study shows is that people with unrecognized heart disease experienced a reduction in heart attack. What it also means is that many, many people truly without heart disease were unnecessarily treated. As you'd predict, the drug manufacturers love this sort of broad, untargeted use of their drugs. It's an approach that brings in billions of dollars of revenues. The article on WebMD, in fact, was accompanied by three ads for various cholesterol drugs on this single page story.

What if only people with heart disease, as identified by CT heart scan scores, were treated? You would indeed witness an even larger reduction in heart attack risk, because the group receiving treatment both has the disease and is thereby at greater risk. Treatment should yield even greater risk reduction than treating broad groups who superficially appear to not have heart disease.

Ignore this nonsense about statin drugs reducing heart attack risk in people without heart disease. If you don't look for it, you won't know you have it. Once again, you can be lots smarter than the media. Get a heart scan and find out if your risk is worth reducing.

Add Boston Globe to the list of heart scan blunders

Yet another piece of mass media misinformation hit the airwaves today. This time it's not from the New York Times or the LA Times, both of which have previously mangled the issues surrounding heart scans. This time it's from the Boston Globe.

In an article titled What is a calcium scan for heart disease, and who should undergo the test?, the report states:

". . . calcium scans may not be a good idea, or prove terribly useful, for most people. For one thing, the scans expose a patient to significant radiation - equivalent to roughly 50 chest X-rays" said Dr. Warren Manning, chief of noninvasive cardiac imaging at Beth Israel Deaconess Medical Center."

As many before him, Dr. Manning is confusing two tests: CT coronary angiography and CT heart scanning. Perhaps we can't blame him: This technology has had its weakest following in the northeast, for reasons not entirely clear to me. (In fact, Track Your Plaque followers have had the greatest struggle obtaining heart scans in that part of the country.) Nonetheless, you'd think he'd have his simple facts straight before talking to the press. Unfortunately, hospital public relations departments will usually just grab whoever they can willing to talk to the press--regardless of their expertise or lack of.


The story goes on to say:

. . ." it's not clear what to do with the results from a calcium scan. If you have diabetes, high cholesterol, high blood pressure, or a family history of heart disease, you already know - or should know - that you are at increased risk of heart problems and should lower these risk factors. So, a calcium scan provides little additional information," Manning said.

"Moreover, even a high score doesn't necessarily mean that the calcified plaque in your arteries is obstructing blood flow, said Dr. Adolph Hutter, a cardiologist at Massachusetts General Hospital."

"The vast majority of people with high calcium tests don't have obstructions and they do fine long-term. So you'd have to test lots and lots of people to prevent one heart attack or sudden death," said Manning.

And if you get a low calcium score, a sign of little or no calcification of plaques, that's not very useful, either, because it could be wrong, or it could be right but lull you into believing you do not have to exercise and watch your diet, cholesterol, and blood pressure levels. "You can still be at risk even if your calcium test is negative," Hutter said.



It is truly shocking how little many (not all, thank goodness) of my colleagues really know about 1) heart scans, 2) coronary disease prevention, and 3) prevention in general. These same "experts" likely advocate high-dose statin drugs and low-fat diets for people at risk. They likely refer patients to the American Heart Association for diet advice and themselves obtain a lot of information from the pharmaceutical industry. The notion of identification, tracking, and purposeful reversal of coronary plaque is entirely foreign to this bunch.

"The vast majority of people with high calcium tests don't have obstructions and they do fine long-term. So you'd have to test lots and lots of people to prevent one heart attack or sudden death." Well, take a look at a graph from a database of 25,000 people undergoing heart scans then observed for several years afterwards:




You can see quite clearly from the curves that heart scan scores very clearly predict your future (if no preventive action is taken). The higher the score, the greater the likelihood of heart attack and death. How much clearer can it get?

The most recent addition to this literature is the PREDICT study which concluded:

Hazard ratios relative to CACS [coronary artery calcium scores] in the range 0-10 Agatston units (AU) were: CACS 11-100 AU, 5.4 (P = 0.02); 101-400 AU 10.5 (P = 0.001); 401-1000 AU, 11.9 (P = 0.001), and >1000 AU, 19.8 (P < 0.001).

In other words, a heart scan score of >1000 is associated with a 20-fold increased risk of cardiovascular events (without preventive efforts). That kind of predictive power and quantitative confidence simply cannot be squeezed out of blood pressure and cholesterol values.

How about the 2008 University of California-Irvine study from the New England Journal of Medicine (do the northeast docs even pay attention to something that is published in their own neighborhood?) that reported:

There were 162 coronary events, of which 89 were major events (myocardial infarction or death from coronary heart disease). In comparison with participants with no coronary calcium, the adjusted risk of a coronary event was increased by a factor of 7.73 among participants with coronary calcium scores between 101 and 300 and by a factor of 9.67 among participants with scores above 300 (P<0.001 for both comparisons). Among the four racial and ethnic groups, a doubling of the calcium score increased the risk of a major coronary event by 15 to 35% and the risk of any coronary event by 18 to 39%.

How about the Prospective Army Coronary Calcium (PACC) project (men average age 43 years):

"In these men, coronary calcium was associated with an 11.8-fold increased risk for incident coronary heart disease (CHD) (p = 0.002) in a Cox model controlling for the Framingham risk score. Among those with coronary artery calcification, the risk of coronary events increased incrementally across tertiles of coronary calcium severity (hazard ratio 4.3 per tertile)."

Calcium score provided additional information even after factoring in the Framingham risk score.

That's just a sample of the studies. There are a number more.

Add to these conversations the fact that, unlike reducing blood pressure or LDL cholesterol, the heart scan score is a quantification of the disease itself. It can also be tracked over time to gauge the success or failure of prevention efforts. To believe that blood pressure reduction or LDL cholesterol reduction is sufficient to eliminate risk is something only a fool would believe.



Contary to the above statements, the data are clear:

--The higher the heart scan score, the greater the risk. This has been demonstrated beyond any shadow of a doubt in at least a dozen published studies. In fact, heart scan scores outshine lipid/cholesterol values several-fold.

--A person with a zero score has a nearly zero risk for cardiovascular events over a 5-year timeline.

--Heart scans are the only quantitative test available of coronary atherosclerotic plaque. This means that they can be repeated to gauge progression or regression. Cholesterol does not do that. Stress tests do not do that.

--Heart scans are not the same as CT coronary angiography.

--The lack of "need" for a procedure does not equate to the absence of disease.

The power of heart scans is that they can uncover evidence for coronary atherosclerotic plaque 10 years before a cardiac disaster strikes. Witness Tim Russert's heart scan score of 210 in 1998 at age 48. 10 years later, you know what happened.

Beware the camipaign of misinformation and ignorance that continues that is hell-bent on maintaining the procedural status quo or locking us into a "drugs for all" mentality.

What's worse than sugar?

There are a number of ways to view the blood sugar-raising or insulin-provoking effect of foods.

One way is glycemic index (GI), simply a measure of how high blood sugar is raised by a standard quantity of a food compared to table sugar. Another is glycemic load (GL), a combination (multiplied) of glycemic index and carbohydrate content per serving.

Table sugar has a GI of 65, a GL of 65.

Obviously, table sugar is not good for you. The content of white table sugar in the American diet has exploded over the last 100 years, totaling over 150 lb per year for the average person. (Humans are not meant to consume any.)

What is the GI of Rice Krispies cereal, organic or not? GI = 82-- higher than table sugar. GL is 72, also higher than table sugar.

How about Corn Flakes? GI 81, GL 70--also both higher than sugar.

How about those rice cakes that many dieters will use to quell hunger? GI 78, GL 64.

How about Shredded Wheat cereal? GI 75, GL 62.

All of the above foods with GI's and GL's that match or exceed that of table sugar are made of wheat and cornstarch. Some, like Shredded Wheat cereal and rice cakes, don't even have any added sugar.

Stay clear of these foods if you have low HDL, high triglycerides, high blood sugar, or small LDL. Or, for that matter, if you are human.

Keep the eloquent words of New York University nutritionist, Marion Nestle, author of the book, Food Politics, in mind:

“Food companies—just like companies that sell cigarettes, pharmaceuticals, or any other commodity—routinely place the needs of stock holders over considerations of public health. Food companies will make and market any product that sells, regardless of its nutritional value or its effect on health. In this regard, food companies hardly differ from cigarette companies. They lobby Congress to eliminate regulations perceived as unfavorable; they press federal regulatory agencies not to enforce such regulations; and when they don’t like regulatory decisions, they file lawsuits. Like cigarette companies, food companies co-opt food and nutrition experts by supporting professional organizations and research, and they expand sales by marketing directly to children, members of minority groups, and people in develop countries—whether or not the products are likely to improve people’s diets.” ??

Are sterols the new trans fat?

By now, I'm sure you're well-acquainted with the hydrogenated, trans fat issue.

Hydrogenation of polyunsaturated oils was a popular practice (and still is) since the 1960s, as food manufacturers sought a substitute for saturated fat. Bubbling high-pressure hydrogen through oils like cottonseed, soybean, and corn generates trans fatty acids. These man-made fatty acids, while safe in initial safety testing, proved to be among the biggest nutritional mistakes of the 20th century.

Trans fatty acids have been associated with increased LDL cholesterol, reduction in HDL, oxidative reactions, abnormal rigidity when incorporated into cell membranes, and cancer. Trans fats still dominate many processed foods like chips, cookies, non-dairy creamers, food mixes, and thousands of others. They're also found prominently in fast foods.

Fast forward to today, and most Americans have become aware of the dangers of trans fats and many try to avoid them.

But I worry there is yet another substance that has worked its way into the American processed food cornucopia that has some potential for repeating the trans fat debacle: sterol esters.


Sterols are naturally-occurring oils found in vegetables, nuts, and numerous other foods in small quantities. Most of us take in 200-400 milligrams per day just by eating plant-sourced foods.

Curiously, the chemical structure of sterols are very similar to human cholesterol (differing at one carbon atom). Sterols, by not fully understood means, block the intestinal absorption of cholesterol. Thus, sterol esters, as well as the similar stanol esters, have been used to reduce blood levels of total and LDL cholesterol.

So far, so good.

The initial commercial products, released in the late 1990s, were Take Control (sterol) and Benecol (stanol), both of which were marketed to reduce cholesterol when 2-3 tbsp are used daily, providing 3400 – 5100 mg of sterol or stanol esters, about 10- to 20-fold more than we normally obtain from foods. Several clinical trials have conclusively confirmed that these products reduce cholesterol levels.

They do indeed perform as advertised. Add either product to your daily diet and LDL cholesterol is reduced by about 10-15%. In fact, in the original Track Your Plaque book, these products were advocated as a supplemental means of reducing LDL when other methods fell short.

In 2008, there are now hundreds of products that have additional quantities of sterol esters in them, such as orange juice, mayonnaise, yogurt, breakfast cereals, even nutritional supplements. Most of these products proudly bear claims like "heart healthy." Stanol esters have not enjoyed the same widespread application. (I believe there may be patent issues or other considerations. However, it's the sterols that are the principal topic here, not stanols.)

Now, here's where it gets a bit tricky. There is a rare (1 per million) disease called sitosterolemia, a genetic disorder that permits the afflicted to absorb more than the usual quantity of sterols from the intestine. While you and I obtain some amount of sterols from plant-based foods, absorption is poor, and we absorb <10% of sterols ingested. However, people with sitosterolemia absorb sterols far more efficiently, resulting in high blood levels of sterols that result in coronary disease and aortic valve disease, with heart attacks occurring as young as late teens or 20s. Treatment to block sterol absorption are used to treat these people.

There are also a larger number, though still uncommon (1/500) of people who have only one of the two genes that young people with sitosterolemia have. These people may have an intermediate capacity for sterol absorption.

Okay, so what does this have to do with you? Well, if you and I now take in 10-20 times greater amounts of sterol esters, do our blood levels of sterols increase?

Several studies now suggest that, yes, sterol blood levels increase with sterol ingestion. One study from Finland, the STRIP Study, showed that children who had double usual sterol intake increased blood levels by around 50%.

Similarly, a Johns Hopkins study in adults with only one of the genes ("heterozygotes") for sitosterolemia increased sterol blood levels by between 54-116% by ingesting 2200 mg of sterols added per day, despite reduction of LDL cholesterol levels.

Even people with neither gene for sitosterol hyperabsorption can increase their blood levels of sterols. But the crucial question: Do the blood levels of sterols that occur in unaffected people or in heterozygotes increase the risk of coronary heart disease? The answer is not known.

Despite the several clinical trials performed with sterol esters, all of them have examined LDL and total cholesterol reduction as endpoints, not cardiovascular events. It is conceivable that, while sterol esters reduce cholesterol, risk for heart disease is increased due to higher blood levels of sterols.

The question is not settled. For now, it is just a suspicion. But that's enough for me to steer clear of processed foods supplemented with these uncertain sterol esters. My previous recommendations for sterol ester products will be removed with the next edition of Track Your Plaque. Until we have solid evidence that there are no adverse cardiovascular effects of sterol esters, in my view they should not be part of anyone's heart-disease prevention program.

(The same argument does not seem to apply to stanol esters, such as that contained in butter-substitute Benecol, since stanol esters are not absorbed at all and remain confined to the intestine.)

The Diabetes Gold Rush

Lou came into the office. Clearly, his program had gone sour.

Lou had initially obtained wonderful control over his heart scan score of 1114, having reversed modestly in his first three years of effort through correction of his multiple causes (including low HDL, severe small LDL, Lp(a), and a diabetic tendency).

But Lou now came into the office red-faced and sporting a big bulging abdomen. Blood sugar? Now in the overtly diabetic range. Lou said that his primary care doctor had suggested that he start on three new medications (glucophage, injectable Byetta, and Actos) to control his blood sugar. His doctor also told him to increase his intake of fibers by eating more "healthy" breakfast cereals like Cheerios.

Lou had apparently done just that (added "healthy" fiber-rich foods) even before his doctor had suggested it. (Lou failed to remember the several conversations we'd had about healthy eating.) Unfortunately, Lou also failed to connect his increased intake of "healthy fiber-rich foods" and his growing abdominal girth (his "wheat belly").

Here's the dirty little secret: Much of the world wants you to be diabetic. It is the health gold rush of this century. "Go West, young man!"




To find out what I mean, you need only ask: Who profits when people become diabetic? That's easy:

The pharmaceutical industry--Diabetes is a booming growth industry, a source of tens of billions of dollars of revenue, poised for enormous growth as the population ages and gets fatter. It is common for a newly-diagnosed diabetic to be given new prescriptions for two or three drugs with a monthly cost of $300. Of course, the chronic nature of the disease make this far more profitable than, say, a two week course of antibiotics. Presently, 70 new drugs are under development.

Diabetes drug maker Novo Nordisk reported a 25% increase in revenues in 2007 from diabetic agents in the North American market, along with near $2 billion increase in profit for the year. Merck's recently-released DPP-4 inhibitor, Januvia, has already sold $668 million in 2007 and is growing rapidly.

The medical device and supply industry. Take a look at the Medtronic quarterly earnings report, detailing the breakdown of their record-setting quarterly revenue of $3.7 billion:

Diabetes revenue of $269 million grew 12 percent driven by sales
of consumables, the accessories required by insulin pump users, and
continuous glucose monitoring products. Revenue from international
sales grew 31 percent over the same quarter last year.


That's what I call a growth industry.

The processed food industry. The food industry is as big or bigger than the drug industry. ADM, Kraft, General Mills all have annual revenues in the $12-50 billion range. There are plenty of others.

When we're told, for instance, that Cheerios reduces cholesterol, we're not told that it skyrockets blood sugar or triggers small LDL. When we're sold whole wheat crackers, Cocoa Puffs (which the American Heart Asscociation says is heart-healthy), or granola bars, hunger is stimulated, impulse to eat more grows, blood sugar escalates, we get fat, we get diabetic. It's a simple formula.

So be aware that there is little incentive among corporate giants in the food, medical device, or drug industries to encourage behaviors that decrease the incidence of diabetes. In fact, there is enormous financial incentive to make sure that diabetes continues to grow at the startling rate it has over the last decade.

To be sure, the drug and medical device industry will also develop better tools to deal with diabetes and its complications. But the very best way to deal with diabetes is to not develop it in the first place.

What else is there?

This question comes up frequently:

Aren't there any alternatives to heart scans performed on a CT or EBT device?

Yes, there are.

First of all, heart scans are performed best on an electron-beam CT device (EBT) or a 64-slice multi-detector CT (MDCT) device. (While they are also obtainable through less-than-64 slice CT devices (e.g., 16 slices and less), I would advise against it because of the excessive radiation exposure and poor accuracy.) CT heart scans are not to be confused with now more popular CT coronary angiograms, which are performed on the same devices but require intravenous x-ray dye and many times more radiation.(See CT scans and radiation exposure and Heart scan frustration.) Heart scans currently form the basis for the Track Your Plaque program, a program of tracking plaque in the hopes of stopping or reversing the otherwise inevitable 30% per year increase.

Let's confine our discussion to people without symptoms, meaning people like you and me sitting at home, not in an emergency room having chest pain or other similar acute symptomatic presentation.

Among the other ways to uncover hidden coronary plaque:

--Heart catheterization--to yield a coronary angiogram. Yes, this does tell us whether coronary plaque is present. However, it is invasive, expensive, and crude. (I've performed 5000 over my career; they are crude, though useful, tools in acute settings like unstable symptoms or heart attack, a different situation.) Coronary angiography is also non-quantitative. While they provide a value like "40% blockage mid-way in right coronary" or "90% blockage in left anterior descending" they do not provide a trackable lengthwise index of total plaque volume. Identifying severe blockages in people with symptoms leads to stents, bypass surgery and the like, but it is not practical nor of long-term usefulness in apparently, healthy people without symptoms.

--Carotid ultrasound--Here's is where a lot of confusion comes from. Standard carotid ultrasound (U/S) performed in virtually every hospital and many clinics will yield crude qualitative results, e.g., "16-49% stenosis (blockage) in right internal carotid artery". The crude value range is because much of carotid U/S is based on flow velocities, not just direct visualization of the plaque itself ("2-D imaging). However, if carotid stenosis of any degree is identified, the likelihood of silent coronary plaque is much greater.

Limitations: The qualitative, non-quantitative nature of carotid U/S make it difficult to follow long-term in a precise way. Also, this is carotid plaque, not coronary plaque. It makes it very difficult to follow carotid plaque as an indirect means of tracking coronary plaque. The two arterial territories, carotid and coronary, do not track together: there are divergences in many people, with carotid plaque absent in some people with advanced coronary plaque, carotid plaque more susceptible to different risk factors than coronary. So carotid U/S is helpful for its own purposes, but not terribly helpful for coronary tracking.

How about carotid intimal-medial thickness (CIMT) obtained also with carotid U/S? CIMT is a useful index of bodywide atherosclerosis. CIMT is simply a measure not of plaque (and is measured in regions of the carotid artery away from plaque), but of the thickness of the lining of the carotid arteries. Everybody has a measurable CIMT, but it thickens as atherosclerosis grows. CIMT is a radiation-free test that takes several minutes.

Limitations: Hardly anybody does it outside of research protocols. I know of no hospital or clinic in my area that performs CIMT, though it is slowly being adopted in some centers. It is also difficult to rely on repeated tests, because there is substantial variation when one technologist or another performs it. CIMT is also a flawed index of coronary plaque. When CIMT is compared to heart scan scores, CT coronary angiography, or conventional coronary angiography, CIMT correlates about 60-70% with the degree of coronary atherosclerosis.

CIMT is therefore a useful test for research, but a distant 2nd choice--if you can obtain it.

--Ankle-brachial index (ABI)--ABI is a crude measure, simply a comparison of the blood pressure (obtained with a blood pressure cuff) in the legs divided by blood pressure in the arms. The ratio is called ABI. Any ABI <1.0, meaning less pressure in the legs compared to the arms, is indirectly indicative of advanced coronary disease. ABI is, in fact, a very powerful predictor of cardiovascular events. If ABI is <1.0, your future risk for heart attack is very high, even in the absence of symptoms.

Limitations: The vast majority of people with heart disease, even those having undergone stents or bypass surgery, have normal ABI's. Virtually all people with high heart scan scores have normal ABI's. In other words, ABI is a measure of very advanced atherosclerosis only.

--Stress tests--I lump all stress tests together in their various forms, e.g., stress thallium, stress Cardiolite, stress Myoview, persantine/adenosine Cardiolite, dobutamine echocardiography, etc. Stress tests are tests of coronary blood flow, not of plaque. Stress tests are useful in people with symptoms, like chest pain or breathlessness, since stress tests are provocative tests that can help determine whether reduced coronary blood flow is the cause behind a symptom, or whether hiatal hernia, esophagitis, gallstones, pleurisy, musculoskeletal causes, or some other process is behind symptoms.

Limitations: Stress test are virtually useless in people without symptoms. This is why people like Tim Russert and Bill Clinton, both without symptoms, underwent several (Russert 3, Clinton 5) nuclear stress tests---all normal. You know what happened to them. Stress tests do not reliably uncover hidden coronary plaque in people without symptoms. Stress tests are, like coronary angiograms, non-quantitative. They are normal or abnormal.


Outside of experimental settings, that's it.

You can probably see why I advocate CT heart scans for tracking plaque. I do not advocate heart scans because I sell them (I don't), because scan centers pay me to say these things (they don't, and in fact my relationship with my usual heart scan centers has become deeply contentious, though I still endorse the technology). I say that heart scans are superior because they are, in 2008, the only way to 1) identify and 2) track coronary plaque that is easy, safe, low-radiation, and reasonably priced (<$200 in Milwaukee at 5 centers).

The need for a technology that allows tracking of plaque, not just initial identification, is also an important distinction. People who've had some measure of atherosclerosis all catch on to this eventually. "Can I reverse it?" is an inevitable question once the disease is identified in some way. So a tool for tracking over time to gauge the success or failure of a program of prevention can be assessed.

Perhaps in 10 years, another technology will emerge as the preferred means to do the same, but better. If that proves true, we will convert to that technology. But today heart scans performed on CT heart scans are the only rational way to both detect, then track, coronary atherosclerotic plaque.

Let's gamble with your health

Let's play a game.

I'm going to list some lipid patterns and you tell me whether or not the person with these values has heart disease.

Patient 1

Total cholesterol 150 mg/dl
LDL cholesterol 75 mg/dl
HDL 50 mg/dl
Triglycerides 125 mg/dl


Patient 2

Total cholesterol 300 mg/dl
LDL cholesterol 200 mg/dl
HDL cholesterol 35 mg/dl
Triglycerides 325


Patient 3

Total cholesterol 300 mg/dl
LDL cholesterol 100 mg/dl
HDL cholesterol 25 mg/dl
Triglycerides 875 mg/dl



Let's say that any one of these profiles is yours. Should you be getting your affairs in order, preparing for your cardiac catastrophe? Should you demand a stress test from your doctor, hoping that it will shed some light on your dilemma? Should you go ahead and go to the all-you-can-eat rib restaurant, content that you will be attending your granddaughger's wedding in 2020 in full health?

If you can tell, you're a lot better at this than I am.

I provide consultation to other physicians and patients on complex hyperlipidemias in my area. In other words, if someone has a difficulty to manage lipid disorder, the doctor sends the patient to me.

Managing these wildly variable values is the easy part. Deciding whether or not heart disease is concealed within the patient . . . well, that's the hard part.

Let's take it a step further: Suppose all three profiles also have 50% of all LDL particles as the abnormal small particles. And they all have a lipoprotein(a) level of 50 mg/dl, an abnormally high level.

How about now: Can you tell whether any or all of these people have hidden heart disease?

What if they are 20 years old? Does that make a difference?

What if they are all females over 65 years--how about now?

If the only tool you have to divine the presence of hidden heart disease is a lipid panel, or even a lipoprotein panel, then the best you can manage is to hazard a guess based on statistical probability. You also assume that this "snapshot" represents the sorts of values someone has had for their entire lives. You cannot factor in the fact that the first person gained 60 lbs in the last three years since completing menopause. You can't factor in that patient 2 smoked two packs of cigarettes a day for 25 years, but quit 10 years ago.

It's also foolhardy to believe that every known cause of heart disease is currently identifiable and revealed by modern-day blood testing.

A heart scan is simply a means to quantify the sum-total of risk factors--causes--that have exerted an effect up until the moment of your scan. It will reveal the quantity of coronary atherosclerotic plaque present, regardless of whether you stopped smoking 20 years ago or lost 30 lbs last year.

For these reasons, nothing can replace the value of quantifying plaque: not cholesterol, not the Framingham risk calculation, not measures of small LDL or lipoprotein(a), not the presence or absence of symptoms. In 2008, the method of choice for measuring plaque remains a CT heart scan. Perhaps in 10 years it will be some other method.

As always, let me remind Heart Scan Blog viewers that I make this point NOT to sell heart scans, which I have no reason whatsoever to do. I say this because we require a tool to track this potentially fatal disease. We require a yardstick for tracking progression or regression. The only tool that suits these purposes in 2008 is a CT heart scan.

Who knows what

You know that cynical old saying:


It’s not what you know, it’s who you know.

In other words, knowing the right person provides you strategic advantage in business, social advancement, etc.

In health, it was often true. Knowing who the better doctors were, for instance, in your city might provide you with access to better care.

Enter the Information Age. You now have access to medical information equal to that of your doctor. You now have access to patient discussions about doctors, their practices, their performance records. There is now a depth and breadth of information on health that was never available before.

I’d therefore turn the old saying into the new Health 2.0 version:


It’s not who you know, it’s what you know.


In health, information now reigns supreme, not knowing somebody else who has the right connections.

Positive: Everybody now theoretically has access to an equal amount of information, since you can access information on any topic just as easily as I can.

Negative: It puts more of the burden on you. If you screw up in health, perhaps you didn’t try to get the best information hard enough.

I love this new development, this emergence of empowerment in health. I call it self-directed health, the individual capacity to exert enormous influence over the quality of your healthcare.

This is obviously a work in progress. All the answers and tools for self-directed care, self-empowerment are not yet available, some haven’t even yet been imagined.

But they are coming.

“Too many false positives”

“Do you really think I need a heart scan?” asked Terry.

“My doctor said that heart scans show too many false positives. He says that many people end up getting unnecessary heart catheterizations because of them.”

At age 56, Terry was becoming increasingly frightened. His father had suffered his first heart attack at age 53, Terry’s paternal uncle had a heart attack at age 56, his paternal grandfather a heart attack at age 50.

Is this true? Do heart scans yield too many false positives, meaning abnormal results when there really is no abnormality?

No, it is not. What Terry’s doctor is referring to is the fact that, in the decades-long process that leads to heart attack, heart scans have the ability to detect early phases of developing coronary atherosclerotic plaque.

Let’s take Terry’s case, for example. Given his family history, it is quite likely that he does indeed have coronary atherosclerotic plaque. Will it be detectable by performing a stress test? Probably not. In fact, Terry jogs and feels well while doing so. While a stress test abnormality that fails to reach conscious perception is possible, it’s fairly unlikely given his exercise routine.

Will Terry’s coronary atherosclerotic plaque be detectable by heart catheterization? Very likely. But why perform an invasive hospital procedure just as a screening test? Should a woman wishing to undergo a screening test for breast cancer undergo breast removal? Of course not.

Is waiting for symptoms a rational way to approach diagnosis of heart disease? Well, when symptoms appear, it means that coronary blood flow is reduced. Stents and bypass surgery may be indicated. The risk of heart attack and death skyrocket. Sudden death becomes a real possibility.

In the 30 or so years required to establish sufficient coronary plaque to permit the appearance of symptoms or the development of an abnormality detectable by stress testing, there were many years when the disease was early--too early to generate symptoms, too early to be detectable by stress testing.

That’s when heart scans uncover evidence for silent coronary atherosclerotic plaque.

Should we call this a “false positive” just because it doesn’t also correlate with “need” for a catheterization, stent, bypass operation or result in heart attack within the next few weeks?

The detection of early plaque is just that: early disease detection.

Imagine, for instance, that the breast cancer that will grow into a palpable nodule or mass detectable by mammogram is detectable by a special breast scan 15 years before it becomes a full-blown tumor, metastasizing to other organs. What if effective means to halt that earliest evidence of cancer could put a stop to this devastating disease decades ahead of danger? Is this a “false positive” too?

In my view, this is the knuckleheaded thinking of the conventional practitioner: “Don’t bother me until you’re really sick.” Prevention is a practice that has become fashionable only because of the push of the drug industry. Nutrition is an afterthought, a message conceived through consensus of “experts” with suspect motivations and allegiances.

So, no, heart scans do not uncover “false positives.” They uncover early disease--true positives--years before it is detectable by standard tests or by the appearance of catastrophe. But that is the whole point: Early detection means getting a head start on prevention.

Do heart scans lead to unnecessary heart catheterizations? Yes, sadly they do. But not because heart scans are false positive. It happens because of unscrupulous or ignorant cardiologists who use the information wrongly. In my view, heart scans should NEVER lead directly to heart catheterization in an asymptomatic patient. Heart scans, as helpful as they are, do not modify the standard reasons for performing heart procedures.

If a car mechanic is dishonest and fixes a carburetor that didn't need fixing, should we condemn all car mechanics? No, of course not. We only need to develop the means to weed out the bad apples. The same applies to heart scans.

Triglycerides divided by five

Here's a bit of lipid tedium that might nonetheless help you one day decipher the meaning of shifts in your cholesterol panel.

Recall from prior discussions that conventional LDL cholesterol is a calculated value. Contrary to popular opinion, LDL is usually not measured, but calculated from the Friedewald equation:

LDL cholesterol = Total cholesterol - HDL cholesterol - triglycerides/5

For the sake of simplicity, let's call total cholesterol TC; HDL cholesterol HDL, and triglycerides TG.

We've also talked in past how a low HDL makes calculated LDL inaccurate, sometimes wildly so. (See Low HDL makes Dr. Friedewald a liar.)

Here's yet another source of inaccuracy of the Friedewald-calculated LDL: any increase in triglycerides.

Let's say, for instance, that starting lipid panel shows:

TC 170 mg/dl
LDL 100 mg/dl
HDL 50 mg/dl
TG 100 mg/dl



You're advised to follow a standard low-fat, whole grain-rich diet advocated by "official" agencies (the diet I bash as knuckleheaded). Another panel a few months later shows:

TC 230 mg/dl
LDL 140 mg/dl
HDL 50 mg/dl
TG 200 mg/dl



(Obviously, I've oversimplified the response for the sake of argument. HDL would likely go down, LDL would change more depending on body weight, small LDL tendencies, and other factors. You'd also likely get fat.)

Now your doctor declares that your LDL has gone up and you "need" a statin agent.

Nonsense, absolute nonsense.

What has really happened is that the increased dietary intake of wheat and other "healthy whole-grain foods" has caused triglycerides to skyrocket. LDL increases, in turn, by a factor of TG/5, or 40 mg/dl. Thus, LDL has been inflated by the triglyceride-raising effect of whole grains.

This is yet another reason why the standard lipid panel, full of hazards and landmines, needs to be abandoned. But calculated LDL in particular is an exercise in frustration.

Though the example used is hypothetical, I've witnessed this effect thousands of times. I've also seen many people placed on statin drugs unnecessarily, due to the appearance of a high LDL cholesterol that really represented increased TG/5, usually induced by an excessive carbohydrate intake, including those commonly misrepresented as healthy such as whole grains.

Who reads The Heart Scan Blog?

In the Heart Scan Blog, I am often guilty of speaking out loud of my varied thoughts on this crazy thing that we've created called the cardiovascular healthcare machine. But I discuss it in the context of asking "How could this be done better--better outcomes, more patient-friendly, more accessible . . . more do-it-yourself?

The last part is the part that throws most people. Do-it-yourself? My colleagues would claim I'm nuts, suggesting that coronary heart disease is something manageable by yourself. In the conventional pathway, after all, coronary disease is that unpredictable, poorly detected by standard tests, condition that then leads to heart catheterization, stents, bypass , and the like.

Several factors distinguish the readers of The Heart Scan Blog that surprised me:

--Nearly 60% are women
--There are a disproportionate number of Asian people. (Can someone explain this to me?)
--A great number have graduate degrees

I believe this tells me that The Heart Scan Blog appeals to a somewhat more sophisticated audience. This, to some degree, warms my heart, since it means that I've captured the attention of some people who may be more discriminating and thoughtful in their Internet surfing.

However, I also lament the fact that these conversations are not achieving the mainstream. After all,
